Implementation: We employ random cropping, random horizontal flipping, and random erasing [1]}. The learning rate uses the \(\rm Learning\ rate_2\)  in Section REF , and the other hyperparameters remain unchanged. Meanwhile, we re-implement the two attention mechanism based models, SE-ResNet-101 [2]} and CBAM-ResNet-101 [3]}, with the same hyperparameters.
